target-ppc: Move ppc tlb_fill implementation into mmu_helper.c
For softmmu builds the interface from the generic code to the target specific MMU implementation is through the tlb_fill() function. For ppc this is currently in mem_helper.c, whereas it would make more sense in mmu_helper.c. This patch moves it, which also allows cpu_ppc_handle_mmu_fault() to become a local function in mmu_helper.c Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
